Raspberry Pi: 10 Great Add-Ons You've Never Heard Of

An interesting accessory for the Pi that comes from Ciseco is the Pi Lite Bright White LED Display. The Pi Lite features a series of white LEDs that can function like a scrolling marquee for a Twitter feed, weather information, or stock quotes in real-time. It can also display static information such as the time or even function to display bar graphs, VU meters, and other dashboard-type applications. It can even play rudimentary games such as Pong and be viewed in direct sunlight.

The unit is completely self-contained and requires no soldering; simply connect the Pi Lite directly to the Pi's GPIO pins. Programming can be done using Python code or downloaded through any number of GitHub open-source projects. The Pi Lite comes in either white or red and is available from Ciseco's website for around $32. View the Kickstarter video here:

This is the fun part, where the industry is small and everyone is still talking to each other. Soon enough, assuming this industry takes off, we will get to the point where big money is involved and everyone talks through their lawyers and PR departments. It is going to be interesting to see if the open source ethos holds up through this. When IBM published their PC bus specification it was a radical move, and they most likely only got away with doing it because Corporate IBM considered PCs to be inconsequential to "real" computing. This generation is starting out from a different base - I am looking forward to seeing where they end up.
